4 Claims.

This invention relates to valves and more particularly to electrically-controlled drain valves.

One of the objects of the invention is to provide a valve which offers a clear passage for a stream of liquid with the least possible danger of clogging. I

Another object of the invention is to provide a valve in which the seat is kept clean to insure proper closing. I

Another object of the invention is to provide a valve including simple and efll'cient operating mechanism which is readily adapted for remote control. According to one feature of the invention the valve includes electrical control means which may readily be controlled through switches at a point remote from the valve. a

Other objects, advantages and novel features of the invention will be apparent from the following. description of the accompanying drawing,

in which:

Figure 1 is a section with parts in elevation of a valve embodying the invention;' and Flgure 2 is a section on the line 2-2 of Figure 1. v

The invention is'illustrated on the drawing as being embodied in a drain valve for an automatic that it might be embodied equally well in valves for many other purposes. As shown, thevalve includes a hollow body It, preferably of cast zinc or zinc alloy, having an inlet opening I! and an integral outlet tube M. An inlet tube l6 extends horizontally through the inlet opening and terminates in'a circular valve seat I! lying in a 345 plane at an acute angle to the vertical. The seat is adapted to be closed by a valve disc 2|! pivoted in the body just above the valve seat l8. If desired the disc 20 may be faced with --rubber or the like to provide a tight seal against the valve seat. I

In order to-operate the valve disc the body l0 is formed with a vertical tubular extension 22 in which a core or armature of magnetizable ma-.

.-terial is movable. The core 24 carries at its flat surface projection-II in the body opposite and at an acute angle to} the valve seat. As the cor'e moves downwardly under the influence of gravity the rollers 26 engage the valve disc 2.

and projection 20 and-wedge the valve disc tight! ly' against the valve seat I! to close the inlet tube It.

. The core It is raised by means ofa solenoid coil Ill around the extension 22 and controlled washing machine although it will be understood by suitable manual or automatic switches, not- I shown. When the solenoid is energized the core understood that numerous changes might be made therein and it is not intended to limit the scope of the invention to the'exact'form shown nor otherwise than by the terms of the appended claims.

What-is claimed is: g

--1. A valve comprising, a hollow body formed 20 with inlet and outlet openings,"an inlet tube extending into said body andterminating in a circular valve seat, a valve member pivotally mounted in said body and movable into sealing position on said seat, a substantially flat surfaced 25 projection in the body spaced from and at an acute angle to the seat, and an operating membermovable across the seat and'having rollers engageable with the projection and the valve member to wedge the valve member against the seat. 30

2. A valve comprising 'a hollow body formed with inlet and outlet openings and a closed tubular extension and having a circular valve seat at the inner end of the inlet opening, a valve disc Hpivotally mounted in the body and engageable at with said seat to close the inlet opening, a flatsurfaced projection in the body at an angle to the valve seat, a core movable vertically in said tubular extension and having one end provided with rollers engageable with the projection and, 40 the valve disc to wedge the valve disc into en-' gagement with the seat, said core being movable downward by gravity to close the valve, and a solenoid coil around the extension to raise the core whereby the vale can open. 1 a

'3. A valve comprising a hollow body formed with inlet and outlet openings and having a tubular extension, an-inlet tube extending into the body through the inlet opening and terminating. in a circular valve seat. a valve disc plvotally -50 'mountedin said body at one side of the valve seat and swingable into sealing engagement with the valve seat to close the inlettube; a projection spaced from and forming an-acute angle with the valve seat,and an operating member movable 55 across the valve seat from said one side and heving rollers engageable with the valve disc and the projection to wedge the valve disc into engagement with the seat.

4-. A valve comprising a hollow body formed with inlet and outlet openings and having a valve seat at the inner end of the inlet opening, a valv e disc pivotally mounted in said body at one side of the valve seat and swingable into sealing engegement with the valve seat to close the inlet opening, a projection spaced from and forming an acute angle with the valve seat, and an operating member movable across the valve seat from said one side and having rollers engageable with the valve disc and the projection to wedge the valve disc into engagement with the seat.
